When it comes to photographs Patricia J DeLois, author of Bufflehead Sisters, is as elusive as a Salinger. When I suggested that an image, even of someone else, might be useful for marketing purposes. DeLois, if only briefly, considered her friend Joan.
"At one time there was talk of Joan posing as me. I first typed Buffleheads on a Mac Classic that I bought from Joan. She pointed out that the software was still licensed to her, so if any issues of authorship arose, she could claim to have written it. Should any appearances on Oprah be called for, I'm sending Joan. I've sent you the book cover."
